Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full behavioral burden. It states the scope ('Alle verfügbaren') and result fields, but it does not explicitly say the operation is read-only, does not mention authentication or rate-limit considerations, and does not describe empty-list or error behavior.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

A single sentence conveys the resource, scope, and result fields with no filler or repetition. It is front-loaded and easy to scan.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a zero-argument listing tool with no output schema, the description names the returned information (category, manufacturer) and the universe of results ('all available'). It could list more exact return fields, but nothing essential is missing for an agent to call it correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

There are zero parameters and an empty schema, so there is nothing for the description to clarify about individual inputs. The phrase 'all available' usefully confirms that the tool is an unfiltered catalog listing, matching the 0-parameter baseline.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description names a specific resource ('Geräte-Vorlagen' / Connector-Katalog) and the expected output fields (Kategorie, Hersteller). This clearly separates it from sibling tools like list_instances, which target a different resource.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is given on when to use this tool instead of alternatives such as list_instances or get_metrics_history. The intended usage is only implied by the resource name and 'all available'; there are no explicit conditions, exclusions, or alternative routing.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
